Answers
Answer:
Step-by-step explanation:
So, there is no end to the number of different solutions obtained on substituting real values for x in the given linear equation. ... Thus, y = 3x + 5 has infinitely many solutions. Hence (iii) is the correct answer.
Answer:
solutions, Write four solutions for each of the following equations: (i) 2x + y = 7 (ii) tx + y = 9 (iii) x = 4y 2. 3. Check which of the following are solutions of the equation x - 2y = 4 and whic not: (i) (0,2) (i) (2,0) (iii) (4,0) (iv) (V2,472) (v) (1,1) 4. Find the value of k, if x = 2, y = 1 is a solution of the equation 2x + 3y=k. Graph of a Linear Equation in Two Variables
